== Function ==
 +
[https://www.uniprot.org/uniprot/CALM_CHICK CALM_CHICK] Calmodulin mediates the control of a large number of enzymes, ion channels and other proteins by Ca(2+). Among the enzymes to be stimulated by the calmodulin-Ca(2+) complex are a number of protein kinases and phosphatases.

== Publication Abstract from PubMed ==
 +
It only takes one mutation: A strategically placed single mutation in a non-enzymatic protein scaffold produced AlleyCat, a small, allosterically regulated catalyst of Kemp elimination. In only seven rounds of directed evolution the enzymatic efficiency of the original 74 amino acid residue catalyst was improved more than 220-fold to achieve a kcat value higher than that of catalytic antibodies for the same reaction, still preserving allosteric regulation.
